Answer:
Explanation:
Using the following formula:
Q = m × c × ∆T
Where;
Q = quantity of heat (Joules)
m = mass (grams)
c = specific heat capacity (J/g°C)
∆T = change in temperature
Answer:
Mass, m = 19466.7 kg
Explanation:
Given that,
Portland cement concrete (PCC) has a density of 150 lb/ft³
We need to find how many kilograms of PCC are required to cast a cylindrical column 1.15 m in diameter and 7.8 m in height.
Since, 1 kg = 2.205 lb
1 lb/ft³ = 16.018 kg/m³
150 lb/ft³ = 2402.77 kg/m³
Density,
m is mass of PCC in kg and V is volume of cylinder
So, the mass of PCC required is 19466.7 kg.

Answer:
What effect does the pH of water have on radish seed germination?
Answer: Option (b) is the correct answer.
Explanation:
The given reaction is as follows.
In this reaction, potassium ions form bond with sulfate ions and results in the formation of potassium sulfate. Similarly, hydroxide ions combine with hydrogen ions to result in the formation of water.
Thus, we can conclude that it is a double replacement reaction occurs because potassium ions bond with sulfate ions to form a salt.
